So, if you can't afford a rotrex/vortex has supercharger, and don't like the roots/eaton chargers, could you use a seadoo jet ski one on a car engine. (Similar centrifugal design).

So take say a puma 1.7l engine with a bit of work done, revs to 8k and pushes out 175hp.

The new seadoo engines are a rotax design with 1.5 - 1.8l, rev to 8.5k and push out between 185 and 300hp. They are supercharged and the top end push out 18psi but the charger does not need a lubrication system, they seem to be sealed/non maintenance systems. The drive will need sorting as they are cog, not belt/wheel driven, but not a difficult job.

So, for $500 you can get a low hours sh charger shipped and taxes to the uk, so what is the snag with putting one of these on something like a puma 1.7 engine (assuming you have an ecu to run it)?

Well a 5 min search suggests that they need rebuilding after 100 goes of use. Also rotax a 2 stroke so the demands on a supercharger are completely different.

Thanks for the reply, this is the mid/upper range engine that I was thinking of, 4 stroke.

Did a search and as you say 100hrs use rebuild but looks like it has some sort of crush washer clutch thing on the shaft which wears. Not sure this will be needed if you stick a pulley on it?
